This commit implements Phase 3 of the CHORUS task execution engine development plan,
replacing the mock implementation with a real AI-powered task execution system.
## Major Components Added:
### TaskExecutionEngine (pkg/execution/engine.go)
- Complete AI-powered task execution orchestration
- Bridges AI providers (Phase 1) with execution sandboxes (Phase 2)
- Configurable execution strategies and resource management
- Comprehensive task result processing and artifact handling
- Real-time metrics and monitoring integration
### Task Coordinator Integration (coordinator/task_coordinator.go)
- Replaced mock time.Sleep(10s) implementation with real AI execution
- Added initializeExecutionEngine() method for setup
- Integrated AI-powered execution with fallback to mock when needed
- Enhanced task result processing with execution metadata
- Improved task type detection and context building
### Key Features:
- **AI-Powered Execution**: Tasks are now processed by AI providers with appropriate role-based routing
- **Sandbox Integration**: Commands generated by AI are executed in secure Docker containers
- **Artifact Management**: Files and outputs generated during execution are properly captured
- **Performance Monitoring**: Detailed metrics tracking AI response time, sandbox execution time, and resource usage
- **Fallback Resilience**: Graceful fallback to mock execution when AI/sandbox systems are unavailable
- **Comprehensive Error Handling**: Proper error handling and logging throughout the execution pipeline
### Technical Implementation:
- Task execution requests are converted to AI prompts with contextual information
- AI responses are parsed to extract executable commands and file artifacts
- Commands are executed in isolated Docker containers with resource limits
- Results are aggregated with execution metrics and returned to the coordinator
- Full integration maintains backward compatibility while adding real execution capability
This completes the core execution engine and enables CHORUS agents to perform real AI-powered task execution
instead of simulated work, representing a major milestone in the autonomous agent capability.

## Problem Analysis
- WHOOSH service was failing to start due to BACKBEAT NATS connectivity issues
- Containers were unable to resolve "backbeat-nats" hostname from DNS
- Service was stuck in deployment loops with all replicas failing
- Root cause: Missing WHOOSH_BACKBEAT_NATS_URL environment variable configuration
## Solution Implementation
### 1. BACKBEAT Configuration Fix
- **Added explicit WHOOSH BACKBEAT environment variables** to docker-compose.yml:
- `WHOOSH_BACKBEAT_ENABLED: "false"` (temporarily disabled for stability)
- `WHOOSH_BACKBEAT_CLUSTER_ID: "chorus-production"`
- `WHOOSH_BACKBEAT_AGENT_ID: "whoosh"`
- `WHOOSH_BACKBEAT_NATS_URL: "nats://backbeat-nats:4222"`
### 2. Service Deployment Improvements
- **Removed rosewood node constraints** across all services (gaming PC intermittency)
- **Simplified network configuration** by removing unused `whoosh-backend` network
- **Improved health check configuration** for postgres service
- **Streamlined service placement** for better distribution
### 3. Code Quality Improvements

This commit introduces secure Docker secrets integration for the ResetData
API key, enabling CHORUS to read sensitive configuration from mounted secret
files instead of environment variables.
## Key Changes:
**Security Enhancement:**
- Modified `pkg/config/config.go` to support reading ResetData API key from
Docker secret files using `getEnvOrFileContent()` pattern
- Enables secure deployment with `RESETDATA_API_KEY_FILE` pointing to
mounted secret file instead of plain text environment variables
**Container Deployment:**
- Added `Dockerfile.simple` for optimized Alpine-based deployment using
pre-built static binaries (chorus-agent)
- Updated `docker-compose.yml` with proper secret mounting configuration
- Fixed container binary path to use new `chorus-agent` instead of deprecated
`chorus` wrapper
**WHOOSH Integration:**
- Critical for WHOOSH wave-based auto-scaling system integration
- Enables secure credential management in Docker Swarm deployments
- Supports dynamic scaling operations while maintaining security standards
## Technical Details:
The ResetData configuration now supports both environment variable fallback
and Docker secrets:
```go
APIKey: getEnvOrFileContent("RESETDATA_API_KEY", "RESETDATA_API_KEY_FILE")
```
This change enables CHORUS to participate in WHOOSH's wave-based scaling
architecture while maintaining production-grade security for API credentials.
## Testing:
- Verified successful deployment in Docker Swarm environment
- Confirmed CHORUS agent initialization with secret-based configuration
- Validated integration with BACKBEAT and P2P networking components
